HOSE-NozzLE.

SPECIFTCATION forming part of Letters Patent No. 270,064, dated January 2, 1863. Application filed-April 19, 1882. (No model.)`

To all whom it may concern Be it known that I, FRANCIS HtcKMAN, of New York, inthe county of New York, and in the State of New York, have invented certain new and useful Improvements in Spun and Drawn Metal Hose-Nozzles; and l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a part ot' this specification. l

This invention relates to hose-nozzles; and the nature ot' my invention consists ina hosenozzle which is formed ot' a drawn and spun metal tube provided with an annular rib or shoulder and an extension beyond the same, in combination with a spun-metal frusto-conical ring, which is screw-threaded, and which is loosely applied on the tubular nozzle and adaptedifor holding the end of a hose thereon and producing a selt'tightened or packed joint when 4there isa pressure of water in the hose, as will be fully understood from the following description, when taken in connection with the annexed drawings, in which- Figure lis a sideview of my improved hosenozzle and coupling, indicating by dotted. lines a rose nozzle or sprinkler as a substitute for the ejecting-tube. Fig. 2 is a diametrioal section through the hose-nozzle, showing a hose coupled to it.

Similar letters of reference indicate corresponding parts in both gures. y

The letter A designates a'sheet-metal tube, which is made seamless by the well-known process of drawing. This tube A may have an ejecting-nozzle, B, formed on it, as indicated in full lines, Figs. 1 and 2; or, if desired, the end of the tube may have a sprinkler or rose-nozzle formed onit, as indicated in ,dotted lines, Fig. 1.

`ilected out of a straightlinc.

April, 1882.

Vternal annular flange, a..

threaded ring or coupling-coll-.tr is slipped over the rear end of the cylindrical portion of the nozzle B, after which, by well-known machinery, an annular bead or shoulder, E, is formed This conical screwon the drawn tubular nozzle by the process of A spinning. The ring C is thus loosely applied on the nozzle, and it is permanently attached thereto. When a single ejecting-nozzle is formed on the tubular portion thereof an. annular bead or shoulder, E', is formed to prevent the said ring `C from slipping oft' this end ot' Athe shoulder E, and for a short distance over l the tube A proper, and the ring Gis set up, as shown in Fig. 2, so as to extend over the end ot' the hose Gr and compress it against the shoulderF, a close joint is formed. Then there is a pressure of water in the hose this pressure will cause a self tightening or packing ot' said joint, andas the pressure increases the joint will in an equal ratio be tightened.

I claim- As a new and improved article of manufacture, a drawn and spun metal hose-nozzle having an annular shoulder and a tubular extension beyond said shoulder, in combination with a spun-metal conical coupling-ring loosely applied on said nozzle and permanently attached to it, substantially as described.

1-n testimony' whereof I affix my signature, in presence of two witnesses, this 18th day of i F. HIOKMAN.
